Abstract (en)

The present invention is a carrier for a double-side polishing apparatus in which, in a double-side polishing apparatus, the carrier is set between upper and lower turn tables to which polishing pads are attached, and a holding hole to hold a wafer sandwiched between the upper and lower turn tables in polishing is formed in the carrier, wherein the carrier is made of titanium. Thereby, there is provided a carrier for a double-side polishing apparatus in which the strength of the carrier itself is high, and at the same time, contamination of a wafer such as a silicon wafer by impurities is suppressed, and sag in a peripheral portion of the wafer after being polished is suppressed.
